Give him red meat and egg with bacon, cut out the carbs and it might be a different story. Cheers!

Eats meat all the time. Doesn’t like eggs.
Sounds like you have a champ in the making, I feed my children as carnivore as possible and they stay comfortably stuffed for hours, but if I add too many fruits or they get the occasional bread/tortilla, they eat even more and get hungrier sooner. It's all about the hunger signals caused by the different hormones we release when we eat certain foods.
